Updating QPR ProcessAnalyzer Server

This page contains instructions how to update an existing Windows installation to a newer QPR ProcessAnalyzer version.

Starting from QPR ProcessAnalyzer 2026.1, .Net 10 is used (instead of .Net 8). If you are updating from an earlier release than QPR ProcessAnalyzer 2026.1, .Net 10 needs to be installed and .Net 8 uninstalled. Both .Net versions work side-by-side, so .Net 8 doesn't need to be uninstalled immediately, but due to security reasons, make sure that .Net 8 is eventually uninstalled.

Update procedure

Follow these instructions to update QPR ProcessAnalyzer to the latest version:

1. Pre-Update Steps:
   • Read the release notes between the original and new releases to identify any special considerations.
2. Download and Prepare:
   • Download the QPR ProcessAnalyzer Server package from the downloads page.
   • Extract the package into a temporary folder (e.g., C:\temp\QPR_ProcessAnalyzer_<build number>).
3. Backup and Stop Services:
   • In the Internet Information Services (IIS) Manager, stop the application pool used by QPR ProcessAnalyzer Server.
   • Backup QPR ProcessAnalyzer Server root folder (by default C:\inetpub\QPRPA).
4. Replace Files:
   • Remove all files in the QPR ProcessAnalyzer Server root folder (by default C:\inetpub\QPRPA).
   • Copy all files from the Service folder of the extracted package into the QPR ProcessAnalyzer Server root folder (by default C:\inetpub\QPRPA).
   • Restore the backed-up appsettings.json file (from C:\temp\QPR_ProcessAnalyzer_<build number>) to the ProcessAnalyzer Server root folder (by default C:\inetpub\QPRPA).
5. Restart Services:
   • Start the QPR ProcessAnalyzer Server IIS application pool.
